Kansas City Chiefs quarterback Patrick Mahomes (15) looks to throw a pass down as Denver Broncos inside linebacker Brandon Marshall (54) puts the rush on during the third quarter on Dec. 31, 2017 in Denver, Colorado at Sports Authority Field at Mile High Stadium.

KANSAS CITY, Mo. — The Kansas City Chiefs began their offseason conditioning program Monday, although the amount of work amounted to meetings and some informal, players-only time on the practice field.

Patrick Mahomes II has been doing all of that for months.

The second-year quarterback has assumed the starting role following the offseason trade of Alex Smith to the Washington Redskins, and he has embraced it with aplomb.

Mahomes had no problem summoning older, more experienced teammates for impromptu workouts at local high schools, and figures he threw passes to every running back, tight end and wide receiver on the roster at least once.

“There were great high schools around where I talked to the coaches and they let us use their fields,” he said, “and I’d have four or five guys a day. They’d come out there and the good thing I have with my teammates is they want to work to get better, so it was easy to get them out there.”

Most guys dropped in for a couple of workouts when they were in town for other business, though a few — such as star tight end Travis Kelce — spent the majority of his offseason in Kansas City.

“He just took control out there on the first day,” Kelce said of his new QB. “That was the biggest thing, seeing he does have control of the room at a young age. He’s not shy taking the lead.”

Most quarterbacks around the league do similar offseason workouts with teammates, especially when there are new pieces in place. It takes time to establish the chemistry and timing required to run the modern spread offense, especially a system as complex and diverse as the one run by Andy Reid.

What makes Mahomes unique is precisely what Kelce said: His age. Mahomes won’t turn 23 until mid-September, shortly after the season starts, making him one of the youngest players on the team.

That must be balanced by the fact that he also plays the most important position.

Yet it’s not as if Mahomes is a rookie being asked to resurrect a floundering franchise. After he was chosen 10th overall he got to spend last season learning under Smith, and then dazzled in a Week 17 start at Denver when the Chiefs already had locked up their playoff seed.

Now he steps under center for the two-time defending AFC West champions, and with more talent around him than any Chiefs quarterback in recent history. He has the reigning NFL rushing leader in Kareem Hunt, Kelce, and a wide receiver group headlined by speedster Tyreek Hill that now includes downfield threat Sammy Watkins.

“He can throw the ball,” Watkins said with a grin. “He led the whole process when we were running routes (Monday). He’s going to be a great leader. Caught a couple balls, dropped a couple too, just by his arm strength. But it’s going to be a fun time. I can’t wait to master this offense.”

The biggest challenge Mahomes could face is making sure everybody gets their touches.

In other words, making sure everybody stays happy.

But as numerous players filed through the Chiefs’ practice facility on Monday, those with a vested interest in getting their hands on the ball said that won’t be a problem. Kelce, Watkins and the rest of them gushed about the selflessness that exists in their new-look locker room.

“Guys don’t have egos. I’ve met them, got to work with them,” said wide receiver Chris Conley, who is coming back from a ruptured Achilles tendon. “I think we’ll have great comraderies, and obviously there’s one ball to go around, but we’re going to make this offense run and shake.”
